To all who/m, t may concern:

Be it known that I, JOHN citizen of the United States, Newark, in thecounty of Licking and SoHornN, a residing at State of Ghio, haveinvented a new and useful Gras Cock, of which the following 1s aspeciiication.

This invention aims to provide a gas cock for a burner for gas and otherfuels of a like sort which is so constructed that it may be adjustedreadily without the use of tools, the device being simple inconstruction and devoid of complicated parts, the construction beingsuch that a. proper adjustment of the gas supply may be attainedreadily, the burner preventing a wasting of the fuel when operatedproperly.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

lVith the above and other objects in view, which will appear as thedescription prooeeds, the invention resides in the combination 'andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimec, changes in the precise embodiment of the inventionshown can be made, without departing from the spirit of the invention.

In the drawings:

Figure 1 shows in side elevation, a device constructed in accordancewith theinvention; Figure 2 is longitudinal section on the line 2-2 ofFigure 1, parts remaining in elevation; Figure 3 is a cross section onthe line 3-3 of Figure 1; Figure 4 is a fragmental longitudinal sectionshowing a modification; Figure 5 is a cross section on the line 5-5 ofFigure 4.

In ca rrying out the invention, as shown in Figures 1, 2 and 3, there isprovided a main tubular member 1 terminating in a tip 2 carrying aprojecting needle valve 3, the tip having inwardly converging passages4, located about the valve 3 and merging into a single inlet opening 5at their rear ends, the opening 5 communicating with the bore of themain member 1. The main member 1 is provided intermediate its ends andnear to its rear end, with a wrench head 6 whereF by the rear end of themain member 1 may be threaded at 7 into the gas supply pipe 8, the head6 abutting against the forward end of the pipe 8.

' dle valve 21 formed A A sleeve 9 is threaded at 10 on the member 1,for adjustment longitudinally thereof, and is supplied with a burnerorifice 11 controlled by the needle valve. At its rear end, the sleeve 9is equipped with a combined hand wheel and guard 12, whereby the sleevemay be rotated, the hand wheel including a disk like body 14 and arearwardly extende peripheral liange 15 housing the wrench head 6.

When the parts are arranged as shown in Figure 2, the gas or the mixtureof gas and air, or other fuel, flows from the pipe 8, through the mainmember 1, through the opening 5 and the passages 4, the air and gas, orother fuel, moving into the chamber 16 which exists betweeny the forwardsurface of the tip 2 and the rear surface of the forward end wall of themember 1, the fuel flowing about the pointed needle valve ,2, throughthe burner orice 11. By moving the sleeve 9 lengthwise of the member 1,through the instrumentality of the hand wheel 12, the needle valve 3 maybe made to control the amount of gas passing through the orifice 11, andif desired, the flow of gas may be stopped entirely. The iange 15 of thelhand wheel 12,y houses the wrench head 6 and it will be impossible toturn the member 1 accidentally by way of the wrench head 6, and loosenthe connection between the member 1 and the Apipe 8.

In Figures 4 and 5, the sleeve 17 is threaded at 18, as before onthemain member 19, the sleeve 18 having a tapered nozzle 2O adapted toYcooperatev with a tapered neeon the forward end of the main member 19,the main member dis- .charging through lateral openings 22 formed in thetapered tothe rear of the needle valve. Aside from the modificationsspecified, the device depicted in Figures 4.and 5 is constructed likethe device delineated in the other figures, and operates inA the sameway.

In a device of the class described, a tubular member provided at itsforward end with a reduced projection and supplied in its forward endwith an opening communicating with the interior ofthe tubular member,the tubular Amember being supplied intere mediate its ends with anoutstanding head, and being threaded externally both in front of thehead and to the rear thereof, a sleeve threaded on the forward portionof the tubuportion of the 'memberf19, y

10 that,

lai1 memberand' having a combustion orifice controlled by theprojection, the Sleeve being supplied at its rear end With a Wheelwhereby the sleeve may be rotated, theY wheel embodying a rearwardlyextended annular flange, the head being housed Within the flange of theWheel against undesirable access, the periphery ofthe head being spacedsuflieiently from the flange of the Wheel so through the instrumentalityof the head, the rear portion of the tubular member may be threaded;intoY a support.

In testimony that I claim the foregoing as my oWn, I have hereto aHiXedmy signature in the presence of tWo Witnesses.
